Since the beginning of software development, developers have attempted to reuse code such as via the use of shared software libraries and repositories. Software repositories both public and private are utilized by software developers to reuse previously developed solutions to software engineering development problems. This is particularly true of large software projects such as those produced by large enterprises or by the open source community. Searching tools allow developers to search for solutions to problems they are attempting to solve so that they do not have to write redundant code and instead may be able to reuse code previously developed for the same or different end product.
